I've been trying to connect my HD500 into my AC15 and to the mixing desk, going for the the split signal. So been connecting left channel (balanced output) into the mixing board, on the preset i have a split signal with an amp with a screamer on left signal path and right channel (unbalanced output) I'm just sending effects to my AC15. But the amp on left signal path (balanced output) effects and comes through on the right signal path on unbalanced output. I have tried panning it on mixer but it just won't go there. so is there a way to send two different signals one to amp and other to mixer? doesn't really make sense that i can not do that without having L6 link.
